Carbon Dioxide Transmitter Co2

Carbon Dioxide transmitter accurately monitors the co2 concentration in the schools, office buildings , and other indoor environments. For increased sensor life , a single beam dual wavelength non dispersive infrared (NDIR) sensor is used to automatically correct the measurement in both occupied and unoccupied buildings against aging effects. The single beam dual wavelength sensor technology provides the highest level of accuracy.

Single beam dual-wavelength sensor advantage:

  • Automatically corrects for aging effects in occupied and unoccupied buildings

  • Perfect for hospitals & manufacturing plants that have occupied 24 hours per day

  • Measures actual unfiltered light intensity directly

  • Eliminates error from incorrect assumptions of gas concentration in theoretical logic assumption methods


Range CO2 : 0 to 2000 PPM or 0 to 5000 ppm.
Accuracy ±40 ppm ±3% of reading
Current 4 to 20 mA
Voltage 0 to 5 VDC or 0 to 10VDC
